I find a few millions apps in the stores (iOS, Android, Windows, Blackberry) and most of them are not made by Apple, Google, Microsoft and Blackberry. It are commercial companies and programmers that make them. Quite innovative.
If none of them suits your need, start making the next one.
I have a Dell51V Axim PDA which is inconvenient to carry around when I have a phone that should be able to do the same. (ie I sync the PDA with my PC through USB, using Outlook Calendar (with Alarms) and an extensively featured Name & Address), also a task list.
What app can I put on my phone & PC that has an extensively featured calendar, an extensively featured Name & address module & a Task module, that has no interaction with an internet connection, ie it needs to be independant only between my phone & PC, and if I change either the phone or PC the sync will update the other
The calendar app needs to have an alarm that can have any sound anywhere residing on the phone & the volume set at maximum phone level that the phone can achieve.
I find the apps supplied with the phone are useless & maufacturers should be more innovative in this field
